Improvement recommendations for the garbage collection process flowmap

Main enhancements to the operations will derive from execution processchanges which are detailed as follows:

1. Implement a comprehensive Start of shift Quick inspection checklist

for the truck to be performed by each driver daily.

2. Improve the supply and procurement processes for fleet spares and

parts to assure that downtime is minimized during truck repairs.

3. Communication improvement to reduce waiting time by proper

scheduling for collection route

4. Organize a schedule for collecting non-organic waste by the third party

subcontractors to avoid delays in coordination as well as excessive

accumulation of waste using extra storage space at facilities..

5. Eliminate the practice of leaving garbage collection trucks with un-

disposed waste at the maintenance station, which is a health concern to

the operation. If the truck ends up all the collection points in its route

should go directly to dump the garbage disposal station at the sanitarylandfill.
